MACHINE FOR MAKING YB0X PARTITIONS.

Appuationmea may a1., 1927. serial No. 195,197.

This invention relates to improvements in machines for making'partitions for boxes and cartons andthe like and it consistsV of the matters hereinafter described and more particularly pointed out in the appended claims.. y l l The machine is of that type adapted to simultaneously operate upon /two different bands or strips of relatively stiff' paper;

passes between suitable dies and punches, to

be operated thereon at predetermined inter-` vals and thereafter slit longitudinally into -ribbons so that the punched openings arel disposed in what afterwards becomes the top edges thereof. While the first band is thusWbeing operated upon, .the other band which is usually much wider, isfed down? wardly toward said ribbonsin a plane at a right angle to the top edges thereof, and the advancing edge portion of said other band punched to provide suitably spaced notches or openings therein which register and interlock with those in the ribbons, after which said edge portion of the band thus interloeked with the ribbons is cut transversely to provide one of the cross bars of the part-ition. After one cross bar has been positioned with respect to the ribbons the ribbons are fed forward the proper distance to receive .another cross bar and so on, enough lto make up the desired size of partition. After the desired number of cross bars have been assembled, with-the ribbons, said ribbons are again fed forward and are then severed transversely and the nished partition is discharged from the machine, ready to be expanded or opened-and placed in a box o carton of the proper size. therefor. r

The primary object ofthe invention is to simplify and improve the construction of the machine whereby it may be readilyadjusted" to vproduce partitions of different" f depths and sizes, without the. necessity of substantially dismantling v the machine; and

changing the feed rolls for the various strips, as: is n ow the practice.

A further object of the invention is to provide an improved punch and die arrangement which permits. a.v ready adjustment thereof to bringI them into the desired position and to provide a novel means for readily adjusting the amount of peripheral movement and consequent feed .of the feed rolls.

I consider at the present time to be the pre'- ferred embodiment thereof.

chine and which will be more fully referred In general the improved machine includes a main frame at' the front end of which is located a vertically reciprocatinl punch to ycoact with a die, a narrow strip of paper being fed between the punch and die to be suitably `punched thereby. Justto the rear of said punch and die is located a pair of transversely extending, horizontally disposed, step by step rotatable, combined slitting and feed rolls, which feed the strip through the punch .and die with a pulling action and slit the punched strip longitudinally-to form the ribbons for the partition. The ribbons passbetween these rolls in a horizontal plane and' are each next engaged by laterally spaced sets of vertically disposed feed rolls, near the rear of the main frame, each ribbon being twisted7 in its length, to pass through -thelast mentioned rolls with its edge disposed in a vertical plane, and with certa-in of the notches -or Vpunches thereof opening lthrough the top thereof.

At the rear end of the machine above said laterally spaced sets of vertically disposed ribbon feed rolls, is a pair of transversely extending, horizontally disposed, step by step vstrip too produce certain openings therein,

spaced in laccordance with the spacingsbeu tween the ribbons, said edge of the wider of the finished boxl partition.

strip afterward becoming the cross lbar strip This advancing edge of the cross bar strip is fed beyond thev punches anddies and passes between suitable 'cutting blades and. into assembled relation with the ribbons after M--which the-blades coact to sever said strip to provide a cross bar and theribbons are again yeach carrying spaced punches 19" bar assembled therewith.' 1When a suitable number of cross bars have been assembled with the ribbons, said ribbons are severed by suitable knives, andy a finished assembled f box partition is discharged from the machine.

Referring now in detail to that embodiment of the invention illustrated in the accompanying drawings, 1 indicates as a whole the main frame of 'the machine which includes upright side frame members 2 and 3 respectively, connected together in suitable spaced relation by a horizontal bed plate 4.

Preferably the parts of the main frame just described ai'e made as an integral casting resting upon a base 5 but as willbe apparent, said parts may also be in the form of separate elements suitably secured together,

At the front end of the main frame, in a plane'above the bed 4, is a transversely eX- tending bridge bar or plate 6 of substantially inverted U-shaped or channel cross section including a top Wall 7. Rising from each end of said bridge plate is aheavy upright guide post 8 secured thereto in any suitable manner. 4In the top wall 7 of said bridge plate is provided a shallow, groove or ,recess 7" in which is seated a die'zholding plate 9, having .an upwardly lopening undercut groove 10therein, said die holding plate and top -Wall 7 having elongated registering openings 11-11 through which the paneliings from the paper strip are discharged as will laterl appear. 12-12 indicates dies arranged in the groove 10 in a manner per initting a lateral adjustment thereof so that said dies may be disposed therein to `operate upon ribbon strips of different widths. Near each end of the die holding plate is Ia block 18, and to each block is secured the associated end of a stripper plate 14 as best shown in Fig. 6. Said stripper plate has the usual opening 13a therein, forthe passage of the punches coacting with the dies' 12-12. Just rearward of the die holding plate 9 is a rod 15 supported by arms 15a secured tothe ends of the stripper plate above the blocks 13. f;

16 indicates a punch carrying cross head, including a flat bottomed intermediate body portion 16a having pairs of spaced arms 16b aty its ends, each pair of arms terminating in an upright bearing sleeve 16,c having a sliding guiding bearing on an associated upright post 8. Between the arms of each pair of arms 16 is provided a wrist pin 17, journalled at its ends in an associated sleeve and end part of the body ortion 16a. lOn vthe lflat bottom of said bo y portion is fixed a punch carrying member 18 and inthe bottom surface thereof is formed an under cut groove 123a asbest shown in Fig-7. 'In this l iio y iai ` ed to coactwith the die 12. These die blocks may be adjusted longitudinally of the lilcinber 18 to register with the dies 12 and may be locked in adjusted position by means of set screws 18".

Means is provided for vertically reciprocating the cross head 16 so that the punches move toward and into operative relation with respect to the dies and then away therefrom and such means is as follows: 20 indicates a transversely extending horizontal shaft ar` ranged below the bridgeplate (i. Said shaft is -of substantial diameter and has reduced end )arts 21 and 22 which are journalled in suita )le bearings in the side frames 2 and 3 respectively, as best shown in Fig. 4. Adjacent eac said shaft is provided with ecccntrics 20a-20, each receiving 'a strap 23 on the bottom end of a. connecting rod 2 3. Each blocks 27 fixed to and extending forwardly iixed to said shaft end, the purpose of "which, will laterappear.

Just to the rear of the! punch and die structure heretofore described is provided a set of combined feed and slitting rolls, which act to pull a substantially narrow strip of ypaper through and` between said punches and dies in a step by' step manner, whereby said strip is unched at desired .intervals and is` therea ter slit into ribbons. Such means is asy followsrRising from each side frame member l2- and 3 respectively, just to the rear of each upright post 8 is an upright open bearing blockl standard 32. In each standard, a pair of top and bottom bearing bl'ocksg33-34 are arranged for a vertical guidedadjustment. 'In' the bottom boxes of both standards is journalled ashaft p 35 and in the top boxes of both standards is journalled a second shaft 36. On said shafts vin suitable position with respect to the punch and die .blocks-'before mentioned is iiXed a coacting set offcircular cutters 35a and 36 respectively. ,The cutters V35HL are spaced end part of reduced diameter,-

Aslit longitudinally into ribbons 4t).

Afrom each other by collars 35" while the cutters 36" are spaced from each other by collars 36", the collars 35" and 36b having peripheral engagement. 'When it is desired 1o adjust the position of the cutters on said shaft with respect to said' punches and dies, the shafts must he removed and collars of a-grcater or less length substituted for those shown. Said shafts 35-36 are geared together to rotate in opposite directions as at 37 in' Fig. 5.

The bottom bearing blocks 34-f34 engage upon helical springs 34 in the bottom end of the associated lbearing standard 32 while an u'ljusting screw 33a is interposed between each top bearing block 33 and the closed top end of the associated bearing standard. By this means the desired tension on the feed rolls so far as the peripheral engagement of tlngmcollars 35b and 3Gb is concerned may be accurately and evenly produced. The left hand end of the top shaft 36 extends beyond its bearing box'33, a suitable distance and secured thereto is a ratchet 38 by which a step by step rotative movement is imparted to said feed rolls 35 and 3G in opposite directions. f

39 indicates a strip of paper of a width sufficient to provide the desired .number of ribbons desired in the finished partition. Said strip which is fed froln a suitable supply roll -(not shown) passes under the stripper plate 14 and under the guide rod 15 and in. between the collars 35" and 3G" on the shafts 35 and 36. itpasscs under the stripper plate over the dies 12-12, the punch operates thereon to punch openings in the strip 39, one foieach cross bar to be used in the finished partition and as said strip passes through the slitting and feeding rolls it is Those parts of the strip thus punched out. fall w through the openings 11-11 in the die plate and top wall 7 of the bridge plate 6 to be discharged from the machine. The punched openings in the strip after slitting provide notches or recesses 41 in one margin of the ribbon together with an opening 42 near, but Within, the other margin of the ribbon as best -shown in Fig. 15. It is'apparent from said Fig. 15 that the notches 41 and 42 are arranged in sets or pluralitics; each spaced a distance apart to receive thecross bars as will later appear and that one set is spaced from the next adjacent set a greater distance as indicated at 43 in said Fig. y15. This portion of greater distance is equal to the distance between alternate notches 41 and said ort-iony is subsequently severed along the dotted lines 43 to .provide the ends of the finished ribbons; Thisljspacing of thenotches is'taken care of by the arrangement of the teeth on the ratchet 38 which is best shown in Fig.13. y

The ratchet 38, which as before described,

llt)

is fixed to the left hand end ofthe tecd roll shaft 36 as two sets of teeth 38 and 381 re' spectively. Associatedwith said ratchet is a pawl 44 pivoted at 44n on a rocking plate 45 loose on the end of said shaft 36 outwardly beyond the ratchet. A spring 44b is so connected to said pawl and plate as to hold the pawl in engagement with the periphery of the ratchet. Said plate 45 is actuated by a rod 46 connected to the crank arm 29 as best shown in Fig. 2. As the plate 45 is rocked, the pawl 44 is moved in onedirection a distance equal to the longer tooth 3 8 whichis a distance equal to thespa-ci-ng between the notches 41 in the ribbon 40. When the pawl 44 is acting on the longer tooth 38b therel is no lost motion so thatthe feed roll is fed a distance equal to the spacing between the` notches 41 on each side of the ribbon portion 43.

The connection between the crank arm 29` and-connecting rod 46 is best shown in Fig. 17. In said ligure the crank arm has a slot 29a therein in which a crank pin block 29b to which the rod 46 is connected, has sliding guiding bearing, said block being adjusted by means of a set screw 29 threaded in the end of said arm 29. Thus when ribbons are desired "wherein the distance between said notches 41 are greater or less than that shown, it is not necessary to change the cutters 351-36a and collars 35b and 36b as heretoforel but only to remove the ratchet 38 and substitute one of proper diameter and i. spacing between the teeth thereofand change the crank pin'block 29" accordingly. lVhen a greater distance between the notches 41 is desired in such ribbons, a'ratchet of larger diameter would be employed -but with the same tooth arrangement as beforeand thecrank pin block 29"' would-be adjustedl to give a longer throw to the pawl. If a lesser distance between the` notches 41 is desired in such ribbons a ratchet of smaller diameter and still with the same tooth arrangement would be employed and the c rank pin block 29" would be adjusted to give a smaller throw to the pawl 44. As lthe ratchet 38 is located on the proximate end of the shaft 36 Moutside the standard 32,- this substitution may beeasily made withoutthe necessity of a substantial dismantling of this end of the machine. It is to be understood' that in operation of the machine,the collars 35h-+36 will pull the strip 39 through the punching mechanism in a step bystep manner and said strip is slit into the ribbons 40 by the cutters 35-36 at this same time. After the ribbons leave the feed and slitting rolls they pass toward the rear end of the machine to what I term a feedl-box indicated asia whole at 4T in Figs. 3 and 10. Dueing their passage to the teed box the ribbons are twisted so as to bring their edges into averticaly plane, with the notches 4l in all the ribbons facing upwardly.

The feed box 4T includes a casting 48 of 'substantially Lshaped cross sect'ion extend- 50 is interposed between'thebottom-of said casting and the top of the bed plate. Said spacer plate is made removable to permit the substitution of such other spacer plate as will correctly position said casting 48 in thel desired plane labove the bed plate. Such an `adjustment is-necessa-ry in changing the niachine to make up partitions of 'different heights. Associated with said casting is an upright front platel and a horizont-a1 top plate 52 roviding th hollow box like structure of tie feed .box,said plates being suitably ixed to the casting.

In the top surface ofthe top plate are provided front and rear, undercut, upwardly opening grooves 521452b extending the full length of the'plate, the latter groove opening intol the interior ofthe feed box. In the bottom wall of thecasting 48`in line with the undercut grooves 52b is an upwardly opening groove 48C. Slidable in the groove 48c is a plurality of rectangular bear-v ing blocks 53 in each of which is journalled an upright spindle 54. The top end 54a of the spindle which is reduced in diameter extends up `through the groove 52" and has fixed thereto a roll`55. Said reduced block 57 slidable in the 'groove 52b so as to be longitudinally adjustable therein, a set screw 58 locking the block in the desired art 5'4a also has an anti-friction bearing 56 ih a ilo position in saidgroove. On the spindle 54 y just above the bearing block 53 is fixed a worm pinion 5 9 which meshes witha worm pinion 60 having a sliding key connection onv a horizontal transverse shaft 61 journalled in ears 5l on the rear side of the front plate 51.v On each side of each pinion 60 is a collar 60l which is so connected to the shaft 61 'as teli-prevent endwise displacement of said pinion.. Said collars carry set screws I 60'J (see Fig. 11) for locking them lto said shaft and said set-screws maybe loosened when it is desired to adjust the positionof theworm pinions'GO on-the shaft The shaft lprojects at its -right 4hand end outV through an upright hollow member 1,30

62 rising from the side frame member 3 at amuser` ber 62. Said plate 65 is undercut longitudinally o n its outer face to provide a guide groove 65" 1n which a plate 67 havmg a bolt 1 and slot connection 67a with the plate 65 is The located so as to be adjusted thereon.

i plat-e 67 Ahas a bearing sleeve 67" in which the end of the shaft 61 has bearing. This construction permits an adjustment of the axial position of the shaft when necessary. 'l`o the extremity of this shaft 61 outside the sleeve (37 is xed a -small pulley 68 driven by a belt 69 from the'pulley 31 on the end 22 of the main shaft, 20. Itis apparent from the foregoing Athat the rollers which are capable of being adjusted into. the desired position with respect to the groove .'52h in the feed lbox 47 are driven at high speed continuously in one direction through the gearing and associated parts just described.

Associated with each roller 55 is an upright tension roller 70. Said tension roller is journalled inthe bifureated rear end of an upright plate 71, the front end of which is pivoted by a bolt 72 to a block 73 arranged `in the groove 52a .in the top plate 52. This block is longitudinally adjustable in said groove intov proper relation with respect to the block 57 in the groove52l? and is locked in the desired adjusted position by a set screw 74 takin through a fixed part of said top plate as' s ownfin Fig. 10. A.

leaf spring 75 (seeFig. 9) removably fixed to that portion .of the plate 52 between the grooves 5252b engages the left. hand side of the plate 71 to bring the roller 70 into yielding engagement with the associated roller 55. ,Onthevother'side of the plate is a vertically adjustable guide member 7 6- under which the top edge of the .ribbon'40 is inserted to be guided thereby between the rollers 55 and 70v respectively. 'lhe guide member 76 has a verticalslot and screw connection 76a with said plate 71 so as to be adjustable to take care of ribbons 40 of different widths. Asy before stated the rollers 55 are continuously' rotating and these rolls actas a secondary ribbon feed in connection with the collars 35M-36". In this manner, those twisted portions of the ribbons 4() between the saidcollars and rolls are`maintained tautagai'nst sagging and at the same time are presented inthe proper On the outer surface of position to receive certain cross bars to make up the finished box partition.

Thev rear face of the feed box wall 48b and the rear edge-of the top plate are so formed as toprovide a rearwardly facing undercut f groove 77 in which one or more blocks 78 have a slidable guidi-ng bearing. Secured to the rear face of said block 78 is an upright plate 79 to the front face of which is secured a ribbon, guideblock 80 having ay vertical guide slot 8(1)" adapted to be'lined up with that portion of the ribbon issuing from the associated feed rolls 55 and 70 respectively.` The plate 79 is secured to the block 78 byv al screw 78" and in the to edge of the plate in line with the guide s ot 80a of the block 80 is a recess 7 "L through `which the ribbon passes, said plate thus acting as the stationary part of a. ribbon severing means as will later appear. In the plate 79 are provided set screws 79" which so engage fixed parts of the feed box proper as to lock the. plate 79 and block 7 8 in the desired position in thel groove 77. Preferably'the ribbon guide block 8() is fixed to the plate 79 by a screw 80".

Spaced rearwardlyfrom lthe plate 79 is a'l horizontally disposed platform orshelf 81 supported from the feed box in the desired spaced relation as by brackets 82-82 in Fig. 9. 0n the front margin of said platform are provided upright ribbon guide blocks 83 each with an upwardly opening slot 83 therein in line with the slot '80 of the feed blocks 80 and slots 7 9n in the plate 79. These blocks 83 which are so mounted on the platform 81 as to be adjustable along the front margin thereof receive the ribbons after they leave the blocks 80 and plates 79 andl guide them in an upright position after they have crossed the space separating the platform 8 1 from the plates 79, so that the associated cross bars of the partition may be assembled with respectl thereto. On said platform near thefront edges thereof, are provided upwardly and forwardly inclined cross bar'guiding tabs 81n the/purpose of which will be referred to later.

I have referred heretofore to what I term the cross bar of the partition which coacts with the ribbons to make upthe finished partition. ,These Vcross bars are cnt from the end of a wide strip of paper 85 fed from a suitable supply roll forwardly of the front end of the machine, the strip being of a vwidth equalling that'of the length of a finished cross bar. ported in a position above the bed 4 of the machine frame, by a table 86 over which it passes rearwardly and is then directed downwardly between a pair ofv transversely extending front and rean feed rolls 87 and 88 respectively, both arranged with their axes in the same horizontal planel This strip 85 is supby .the cross member 64.

extending leg 92a which isy capable of a slight yielding' movement. The blocks 89 in both guides 91-91 for the front feed roll 87 each abut against a set screw 93 in the forward end of the associated guide 91 while the blocks 90 in bothl guides are each engaged by a stem 94 slidable through the rear end of the associated guide 91. Means are provided to quickly bring the feed rolls 87-88 into a good feeding contact for the cross bar strip 85 and whereby the rolls may be' quickly separated for the threading of the strip 85 between them.

95 indicates a shaft arranged parallel with and inthe same horizontal plane as that of said feed rolls, said shaft being located between the rear ends of the. box guides and said vlegs 92 of the plates 92. This shaft is journalled in ears 96 fixed, one .on the rear end of each box guide as best shown inv Fig. 3. On'each end ofsaid shaft is a pair of oppositely disposed cams 97-97, one to engage the 'stem 94 and the other to engage the leg 92a. When the shaft. 95 is turned in one'directi'on the cams will engage the stei'ns, the legs acting to vyield slightly and to.. go under tension and thus hold the feed rolls in contacting relation., The shaft 95 has a crank 95 (see Fig. 2) for turning the same. When it is desired to release said rolls so that the strip 85 may be threaded therebev tween, it is only necessary to turn the shaft in the other direct-ion to bring the cams out of engagement with the box guides and legs after which the rear roll may be moved away from the front roll.

i One of said rolls naanely the front roll 87 is they driven roll and a step by step movement is imparted thereto as follows: The

shaft extension 87 of said roll at. the .right handf-fsideof the machineis extended outwardly beyond' the side frame 3 where it Y has fixed to it a ratchet 98. Loose on said shaft is a rocking plate 99 which carries a pawl 100. The Vplate 99 is rocked by a rod 101 'connected at one end to said plate and at the other end to any adjustable crank pin 102 on the crank arm 30 before mentioned.`

As the ratchet and pawl structure and the adjustable crank pin are of the same structure as that heretofore described forrotating thou ht necessary to desc'ribe'the same in detai again.

The strip supporting table 8G is inclined downwardly and rearwardly and carries a shaft 8G journalled at one end in a bracket 85 on one box guide 91 and the other end of this'shaft is threaded into a similar bracket 85 on' the otherv guide 91. The rear end of said table carries a shaft 8Gc arranged in standards 86 rising from the bearing standards 32 as best shown in Fig. 2l. 4A Lcrank 86e is lfixed on one end of the shaftl 8G which when turned in one direction or other, adjusts said table laterally. As said strip passes over the table it is guided by flanges e as best. shown Iin Fig. 2.

After the strip 85 leaves the feed rolls 87-88 it passes downwardly against the vertical iat rear face of the cross 1neniber'64 before mentioned as being made integral with the hollow upright members 62 and 63 respectively. In said cross member is an opening 64 the rear end of which is formed to provide a shallow recess ,64b in thefrear vflat face of the cross member 64. In said recess is arranged a die supporting plate 103 with an undercut groove in' its rear face. The plate 103 is secured in place/by screws In the groove 103 is arranged a plurality of die members 104 each having a die opening 107/l therein. These die members are longitudinally adjustable in the groove and are locked by set screws 104b as best shown in Fig. 8. The bottom edge of said member Gf-t is inclined upwardly and forwardly and has secured thereto a fixed cutter bar 105.

Extending rearwardly from each end of the cross member 64' is a horizontally disposed guide post vIOGaIfranged inthe plane of the-die bloc-ks 105" and upon' which a cross head casting 107 has sliding guided reciprocating movement toward and away from the cross member 64, said c ross head having a bearing sleeve 107 at each end, one engaged on each post 106. Each sleeve 107:L has a depending ear 107b for a purpose to appear later, and a laterally extending stud 107 to which is connected one end of a connectingI rod 108, the other end of said rod being conneet-ed to an associated strap 23a before mentioned. lhrough ythese straps (on the eccentrics 20a) and'conne'cting rods 108 a reciprocating movement is imparted to the cross head 107 towardV and awayfrom the cross member 64.

The front face of the cross head 107 is made vertical and flat and secured thereto is I a punch block plate 109 having an under cut groove in its front face. Said groove is adapted to receive a punch block 110 one .for

each die block 104, each block carrying a punche\1f10 to coact with-the die opening 10i, There is a coacting punch and die for each ribbon and said punches arc spaced laterally a distance corresponding to that of the ribbons.

fthe'cross head 112 will move downwardly` and forwardly to bring the cutter bar'111v into position with respect tothe fixed cutter bar 105, and thus sever the strip 85 along aline coincident with respect to the meeting edges of said cutter bars. When the cross head 107 moves outwardly the cross head 112 will of course move outwardly on the posts 113.

As the advancing edge of the cross bar strip approaches the punches and dies 110 and 104 respectively, said edge which faces downwardtv is operated upon to form therein openings 115, which are best shown in Fig. 1G. This advancing edge of the strip after it passes the plane of the meeting edges of the cutter bars and before severance thereby is fed to engage the ribbonstrips 40,.-the openings -115 in said edge registering with and entering into locking assembled relation with the notches 41-42 of said ribbons, the openings 115 including shoulders 115a to lock in the openings 42 of said ribbon strips.

As this advancing edge portion of the strip is moved into assembled relation with the ribbons, its` extremity will engage upon the platformrl: which l'mits its movement. This as before intentional is before lseverance ofthe strip'85 sothat, that portion of said strip 85 between said edge and the plane of the punches and dies will have therein, the openings" 115 arranged in vertical spaced relation corresponding` to the height of the punched portion. -'After this punched edge portion ofthe strip 85 has been aas-,

i sembled with the ribbons the cutter bars ling the severance.

111 and 105 coact to sever said strip into a finished cross bar 116. During this severance, the end 'parts ot said cross bar engage against the guides 81*1 on the platform 81 to prevent the flexing forward of said cross bar under the action of the cutter bars dur- After one cross bar has been severed vfrom the strip another is'fed into position and then-severed as before, all as best shown in Fig. 12, the ribbons 40 advancing step bystep. The pawl and ratchet feed for the rolls 87 and 88 is so arranged however, that when the vportion 43V of the ribbons 40 enters the space between the guide blocks and 83 the pawl 100 is clicking back over the ratchet 98 and said feed rolls remains passive and inoperativeto feed the cross bar strip and said ribbonsy are then severed along the line 43 before mentioned in a manner now to be described.

Associated with the plate 79 which forms the stationary part of the ribbon severing means, 'is a coaeting removable cutter bar 117. Each cutter bar which is provided with a cutting edge 117a at its top end to coact with the slot 793L in an associated plate 79, is pivoted at a point between 'its ends bya stud bolt 118 to said plate 79 and block 78. A tension spring 119 is interposed between said bar and a nut and .washerv 119a on said bolt to 'maintain proper shearing coaction between said parts. The bottom end of each cutter bar is connected by a bolt and slot adjustable arrangement 120 with a transversely extending trip bar 121. .That end of this bar adjacent the hollow upright member 63 is pivotally connected as at 122 with a downwardly extending arln 123 fixed on a sleeve 124 that is rotativelymounted on a longitudinal shaft 125. Said shaft is located a lshort distance above the bed plate 49 and is supported at its front end by a 'bracket 125a on the. bed 4. In the upright hollow member 63 is fixed an inwardly extending horizontal stud 126 to overhang the shaft 125. Loose on said stud 126, is a ratchet wheel 127. and also loose on Said stud is a rocker plate 128. Said platecarries a spring pressed pawl 129 to engage'with the teeth of the ratchet and rocking movement is imparted to said plate by a link 130 operatively connected 'at one end to said plate and at its other end to the stud 107c on the. sleeve 107 before mentioned. The rocker plate and ratchet are held on said stud 126 against displacement by asuitable nut and washer as bestshown 1n Fig. 9. Projecting inwardly from said ratchet is a stud 131 adapted in the rotation of they ratchet to engage a roller which pull on the bar 121 against the action' of the spring 134. This causes the cutter bars 117 to swing in a manner so that each cutting edge 117,swings across the face of the plate 7 9 and severs the ribbon strips 40-40 and the .finished box artition falls' ofi' the platform 81 onto a ta le 135 at the rear end of the machine where they are removed forl use or shipment.

In lthe cross member`6'4, suitable. openings areprovided through which they connefting 'rods- 108 and rocker arm 130 pass, allas best shown in Fig. 8.

My improved machine has many advantages. It may be readily adjusted to produce box partitions of different heights as well as partitions wherein the number of ribbons and cross bars together 'with the distances of intersection, may be readily made up without requiring a dismantling ofthe machine to substitute different sets of feed rolls for different sizes ofpartitions.' The punches and dies may be quickly adjustedy into the desired position, and the other mechanisms readily coordinated therewith..

The machine is accurate in punching and assembling the various ribbons-and cross bars and in severing thek same when necessary. Ilt requires no further watching after once set and started further than to sce thatl a sufficient supply of strips is provided and that the finished partitions 4are moved from the table, at the rear of the machine.
